摘要
提出了通过多光束干涉产生衍射不变光场的方法,系统的研究了多光束的相位改变对输出光场的影响,这一方法可以用来产生衍射不变周期阵列光场,如拓扑荷为1的阵列光学涡旋,这在光学微操控、粒子分流、材料加工处理领域有着重要的应用价值.
We introduced a method for production of diffraction free beam on the basis of beams' interference, studied the effects on the output field from the phase change of the interference beams. This method can be used for production of diffraction free beams with array, such as the optical vortices with topological charge equal 1. This can be used for micro-particle manipulation, optical sorting, material processing or other fields.
